The Architecture, Engineering & Construction (AEC) industry strongly affects the economy, the environment, and society as a whole. However, when compared to other industries, its productivity, over ...recent decades, has been very low. Currently, the AEC industry is undergoing major changes, mostly driven by the implementation of Building Information Modeling (BIM), and the integration of new technologies. When coupling these with Lean principles, there is the potential to improve the productivity and efficiency of construction projects. Although Lean Construction and BIM are approaches with quite different initiatives, both have a profound impact on the industry. Many studies have shown the advantages of the Last Planner System (LPS), yet its integration with BIM technology has not been fully exploited. The Last Planner System of Production Control – a production planning system designed to produce a more reliable project plan – and the principle of promoting continuous improvement are introduced. By capitalizing on the synergies between Lean Construction and BIM, this study proposes a construction management tool that combines the LPS with the 3D visualization of construction projects to improve productivity and reduce construction waste. The prototype tool is mainly aimed to be used as a construction management tool during the construction phase. The tool allows dividing construction projects into work zones, obtaining a fully automated quantity take-off, and offers a color-coded 4D construction simulation for the short-term planning process of the LPS. It allows for a systematic evaluation and analysis of the construction planning in terms of productivity, manpower allocation, and quantification of waste considering the short-term planning process, which promotes continuous improvement of future construction planning.
•There are many synergies between BIM and Lean Construction.•This paper presents a tool to exploit the information in BIM to support the LPS.•The proposed tool promotes a continuous improvement of future construction planning.

The construction sector consumes a massive amount of resources, produces a large volume of emissions, and generates large-scale waste. Earlier studies considered green, lean, and Six Sigma (GLS) ...approaches as being critical in the construction process for the optimum use of resources, cost reduction, quality improvement, and sustainability. Pakistan's construction sector is struggling to implement sustainable and improved construction processes. This work attempts to analyse barriers to the GLS construction process (GLSCP) through a literature review and expert opinion. During brainstorming sessions, a group of experts validated the barriers and developed contextual relationships among them using a questionnaire. An 11-level hierarchal model was developed by implementing interpretive structural modelling (ISM) methodology. The Matriced Impacts Croise's Multiplication Appliqée a UN Classement (MICMAC) technique was applied to delineate these barriers into the categories of ‘driving’, ‘linkage’, and ‘dependent’. While the findings indicate that all barriers are critical and play a role in hindering the application of GLS in the construction process, the top five critical barriers to GLS are an unstable political environment, lack of government policy, lack of customer involvement and awareness of GLS, lack of funds, and lack of top leadership support for GLS adoption. This work may assist the government, policy-makers, and managers by providing insights into the barriers and in developing strategies for the possible adoption of GLS concepts for sustainable construction and improved quality.
•Pakistan’s construction industry is facing challenges in sustainable construction because of a lack of green, lean, and Six Sigma implementation.•Regarding the barriers to green, lean, and Six Sigma, driving and dependence power and their interrelationships are framed by integrating ISM and MICMAC methods from a construction sector perspective.•An unstable political environment is a major barrier driving other barriers to green, lean, and Six Sigma implementation.•Lack of government support is the second most important barrier to green, lean, and Six Sigma implementation in construction, which is driven by an unstable political environment.•Implications for policy makers and managers are given to overcome the explored barriers.

Although automation has been actively and successfully used in different industries since the 1970s, its application to the construction industry is still rare or not fully exploited. In order to ...help provide the construction industry with an additional incentive to adopt more automation, an investigation was undertaken to assess the effects of digital fabrication (dfab) on productivity by analyzing the cost and time required for the construction of a robotically-fabricated complex concrete wall onsite. After defining the different tasks for the conventional and robotically fabricated concrete wall, data was collected from different sources and used in a simulation to describe the distribution of time and cost for the different construction scenarios. In the example, it was found that productivity is higher when the robotic construction method is used for complex walls, indicating that it is possible to obtain significant economic benefit from the use of additive dfab to construct complex structures. Further research is required to assess the social impacts of using dfab.
•Digital fabrication (dfab) has great potential to advance the construction industry.•Productivity is higher when dfab is used for complex structures.•No additional cost from robotic fabrication if the complexity of the wall increases•Dfab will transform current roles in the planning and execution of projects.•Further research is required to assess the social impacts of dfab.
